abstract |
The invention relates to copolymers containing 0.01 to 35 mol%, based on the total monomer composition, of one or more polymerized perfluoroalkyl group-containing monomer units, 55 to 99.99 mol% of one or more polymerized N-vinylamide monomer units and 0 to 10 mol% % of one or more other comonomers, a process for the preparation of the copolymers and their use as emulsifiers and dispersants in aqueous systems. |
